1 Claim.

The present invention relates to new and useful improvements in suctioncleaners for floors and floor coverings of the type including a suctionnozzle having mounted therein a motor driven l3 rotary brush and has forits primary object to provide, in a manner as hereinafter set forth, acleaner of this character comprising a novel construction andarrangement of swinging beater operable in the nozzle forwardly of thebrush.

Another important object of the invention is to provide a suctioncleaner including a beater forwardly of the brush, together with novelmeans for operatively connecting said beater to said brush for actuationthereby. I

Other objects of theinvention are to provide a suction cleaner of theaforementioned character which will be comparatively simple inconstruction, strong, durable, highly efficient and reliable in use,compact, light in weight and 2a which may be manufactured at low cost.

All of the foregoing and still further objects andadvantages of theinvention will become apparent from a study of the followingspecification, taken in connection with the accompanying drawingswherein like characters of reference designate corresponding partsthroughout the several views, and wherein:

Figure 1 is a side elevation with parts broken away, of a suctioncleaner-embodying my invention.

Figure 2 is a view in bottom plan of the forward portion of the cleaner.

Figure 3 is a vertical sectional view, taken substantially on the line3-3 of Figure 2.

Figure 4 is. a detail view in perspective of the beater.

Figure 5 is a detail view in front elevation of one of the elementswhich operatively connect the beater to the brush.

Figure 6 is an elevational view of one end portion of the brush havingmounted thereon an eccentric for actuating the beater.

Figure 7 is a view in end elevation of the brush.

Referring now to the drawings in detail, it 45 will be seen that thereference numeral 1 designates a suction nozzle having joumaledtransversely therein a rotary brush 2. The brush 2, as usual, isoperable in the rear portion of the mouth or inlet opening of the nozzle1.

The rotary brush 2 is operatively connected by an endless belt 3 to apulley 4 which is fixed on the shaft of an electric motor 5, said shaft,as

of levers which are pivotally mounted for swinging movement in avertical plane, as at 9, on the side walls of the suction nozzle 1forwardly of the rotary brush 2. Extending between the forward endportions of the levers 8 is a beater bar 10 which is operable in themouth or inlet opening of the nozzle 1, as will be understood.Eccentries 11 are fixed on the ends of the rotary brush 2 and the levers8 are operatively coupled thereto through the medium of connectors whichare des-' ignated generally by the reference numeral 12, said connectorsincluding rings 13 journaledon the cocentrics 11 and from which dependarms 1% which are pivotally connected to the rear end portions of saidlevers'8. This is illustrated to advantage in Figure 3 of the drawings.

It is believed that the operation of the invention will be readilyapparent. With the fan 6 in operation the floor covering, which isdesignated by the reference numeral 15 in Figure l of the drawings, isdrawn upwardly toward the suction nozzle 1 where it is engaged by therotating brush 2. As the brush rotates swinging movement is imparted tothe levers 8 thus rapidly moving the beater bar 10 upwardly anddownwardly for effectively beating the floor covering in advanced of thebrush.

It is believed that the many advantages of a suction cleaner constructedin accordance with the present invention will be readily understood, andalthough a preferred embodiment of the invention is as illustrated anddescribed, it is to be understood that changes in the details ofconstruction and in the combination and arrangement of parts may beresorted to which will fall within the scope of the invention asclaimed.

What is claimed is:--

- In a suction cleaner, a suction nozzle and a motor driven rotary brushoperable in said nozzle, eccentrics fixed on the ends of the rotarybrush, a pair of levers pivotally mounted intermediate their ends, onthe side walls of the nozzle forwardly of the brush, a beater barextending between the forward end portions of the levers, and meansoperatively connecting said levers to the eccentrics for actuationthereby, said means including rings joumaled on the eccentrics, and armsprojecting from the rings and pivotally connected to the rear endportions of the levers.

usual, also having mounted thereon a rotary suction fan 6 which isoperable in the chamber '7. The reference numerals 8, 8 designate a pair
